You can program one cheaply using GCC which has supported ARMs for a long time.

Divide is not important, 6502 had neither multiply nor divide or even addition without carry. That was still enough to make the world's first spreadsheet, in less than 64 KB RAM.

This board is around 10$.
processor shoud be around 48 MHz speed, 32 Kbytes of Flash memory and 4 Kbytes of SRAM
Toolchain can be free with GCC ARM.
Probably below 1Watt but it depends on the application running.

m3 is way better and costs as much.

Single-dollar amounts in low quantities on Digikey.

Though you'll need to either buy SMT-to-DIP adapter boards from Ebay, or make your own.

For a programmer, you can use a Bus Pirate or a Segger J-Link, depending on budget. Software toolchain is just GCC.

could mebbe solder those little legs
isn't like a pentium .. there are gaps
for $1 a 32 bit processor
